Abstract

Search and Rescue (SAR) systems are used to locate, stabilize and extract individuals in distress. Many aircraft have Flight Management Systems (FMS) that have SAR capabilities. The SAR pattern initialization data is normally entered through the Multifunction Control Display Unit (MCDU) of the FMS. On some aircraft the Multifunction Control Display Unit (MCDU) of the FMS system is replaced by a Graphical User Interface (GUI) Unit. To create a SAR flight plan in a GUI display system, it would be necessary to develop the windows, commands and data processing interfaces required to enter the SAR pattern definition data. This increases the overall cost of the system. The present paper aims to insert the SAR flight plan pattern in the FMS graphically without increasing the cost of the system.

Search and Rescue (SAR) Interface with Loadable Pattern Data File

Vic Tarbutton ABSTRACT

Search and Rescue (SAR) systems are used to locate, stabilize and extract individuals in distress. Many aircraft have Flight Management Systems (FMS) that have SAR capabilities. The SAR pattern initialization data is normally entered through the Multifunction Control Display Unit (MCDU) of the FMS. On some aircraft the Multifunction Control Display Unit (MCDU) of the FMS system is replaced by a Graphical User Interface (GUI) Unit. To create a SAR flight plan in a GUI display system, it would be necessary to develop the windows, commands and data processing interfaces required to enter the SAR pattern definition data. This increases the overall cost of the system. The present paper aims to insert the SAR flight plan pattern in the FMS graphically without increasing the cost of the system.


1. Introduction

Search and Rescue (SAR) missions are carried out to search and provide aid to people who are in distress or imminent danger. Many aircraft are often used to conduct SAR operations for air rescue. Many Honeywell Flight Management Systems (FMS) have search and rescue capabilities. Once the search and rescue option is selected, the FMS displays the SAR pattern initialization pages using the Multifunction Control Display Unit (MCDU) so that the crew can define the pattern that is to be inserted into the flight plan.

A typical MCDU has a keypad and other hardware that directly interfaces with the FMS. Now-a-days some aircraft have a graphical user interface that allows user to interact with the FMS through graphical icons and visual indicators. There is a need for a GUI interface that allows the crew to perform SAR operations in the same manner as with an MCDU.

One of the solutions to the above problem is to develop the windows, commands and data processes required to provide the same type of SAR interface in GUI system. However this leads to an increase in the overall cost of the system and, in some cases, is not commercially feasible to implement. An alternate solution discussed in the prior art to the existing problem is to create a flight plan offline that is similar to the flight plan in MCDU and download them onto the aircraft. This capability can be used to create flight plans that would look like a SAR pattern, but because of the geometry of some of the patterns, the FMS may find it difficult to fly the pattern correctly.

Therefore, a solution that addresses the limitations of initializing SAR flight plans through a GUI as described above is required.


2. Solution

The invention resolves the above mentioned problems by introducing an external device that will interface with the FMS. The external device captures the parameters needed by the FMS to construct the desired SAR flight plan.

The proposed external device is presented in the figure 1. The external device can be any portable device such as an iPad or a handheld tablet or p...
